PICKING-MOTION.

Specification of Letters Patent. Patented Dec, 14, 1909. ApplicationledJuly 24, 1908. Serial No. 445,154.

' To all whom it may concern.' f.

l suitable for loomsfor weaving all kinds of ed parts for operatinfabrics.

The principal objects of the invention are to provide a constructionwhich can be apl plied tov all kinds o f looms and which is soconstructed that it willbe greatly simplified, and the expense ofmanufacturing correspondingly decreased; also to provide a constructionin which the repairs will be so materially lessened that a loom xer cankeep several additional looms in repair; which will be capable ofvoperating ata higher speed than has heretofore been obtained, and-in-which the shuttle driver will push the shuttle out ofthe box in arectilinear manner. l Some of the above named objects are securedlargely in providing a construction in which substantially no leather-0rwood is used, the picker-strap, raw-hidepicker, picker-stick,sweep-stick, sweep-strap,pow`er strap, and heel-strap, as these part-sare now known in looms, being entirely done away with', and no strapsbeing required except' the harness lstrapand driving strap. In the placeof these features, parts are employed which do not wear out and breakasrapidly as the leather and wooden parts.

The invention alsoinvolves 'an improved construction in which thepicker-roll is mounted directly on the main shaft so as to simplify theconstruction of the connect.-

the sweep arm. Another feature-o the invention consists in the provisionof means whereby-if the shuttle, driver is caught in the box either.'`

' vAnot er feature'O th'inverition. consists.

forgiving the above mentioned rect inear position.

ing each rotation of the main .shaft.

motion which, like the rest of the mechanism,'can be attached to anyform of lever,

and is of universal application, and an important feature is theprovision of means whereby the wear on the picker due to the rubbingaction thereof will be substantially eliminated. A

The ,invention also embodies other improvements in the details of thepicker and shuttle driving mechanism as will appear hereinafter.

Reference is to be had to the accompanying drawings which illustrate oneform of 'the.invent1on, and in which,

Figurel is a front elevation of a prac-` ticable form of the pickingmechanism with the other parts of the loom omitted; Fig. 2 is afragmentary end view showing the operation vof the picker roll; Fig. 31s an elevation of the picking shaft and connected parts looking at itfrom the inside of the loom; Fig. 4 is an end view of a portion of thesweep arm showing the shaft in sectionyFig. `5 is a plan ofthe shuttlebox guide and picker; Fig. 6 is a sectional v1ew -of one oftheself-oiling guides; and, Fig. 7

is a front view ,with the parts in another .For the purpose of laccomplishing the above mentioned results and` others which will .appearhereinafter, the invention is shown ina simple form in which it can beapplied .to looms o f'substantially all types, whether for weavingcotton, woolen or other fabrics, and which involves a frame .10 whichmayv This frame su ports the main shaft 11 on which is direcfly mounteda picker roll extension 12 carrying the picker-roll 13 heldl in place bya fiat spring 130 endaglng a sclot inthe end of the stud 131. Thispicker roll is designed 'to come in contact with the -upr perf curvedcam surface 14 of a lever 15 so as to depress the outer end of saidlever durlever-15 is provided with va notch 16v in the be l:of ordinaryconstruction.

The

end: thereof for engaging a-roll 17 on a and 18 are lever 18.` Both the'levers shown as pivoted on axes .parallel .to the axis of the mainshaft.' Through aconnect;

ing -rod 19v the lever 18" operates anarm 20 on thepicking shaft 21 soas lto -oscillate said Vv shaft once "during each complete rotation ofthe main shaft. The picking shaft 1s mounted lin bearings on brackets 22fixed to the inside of the frame and/extends along the inside thereoftransverse to the axes of the main shaft and levers. It will-be lseenthat the operation of the picking shaft 21 is positive and that it mustoseillate every time the main shaft rotates. Consequently, if any` thingshould occur to stop the picker-lever,

something might break. In order to avoid this the picker shaft isprovided with a pair of brackets 25 .in which slide one or more rods 26having collars 27 t thereon, and springs 28 'for forcing them in onedirection. These rods are provided with beveled ends 29 fittingcorrespondingly shapeddepressions 30 in the hub of the sweep arm 31which is loosely mounted on a collar 32 on the picking shaft. From thisconstruction it will beseen that,the springs 28 being of lever.

sufficient rigidity, the motion of the picking shaft will be transmittedto the sweep arm under all ordinary conditions, but ,in

case of extraordinary resistance, the ends of the rods 26 vwill bepushed out of -the depressions 30 and rthe shaft 21 can then oscillatewithout breaking. the parts which are connected with it.

l 11e picking sweep arm 31'is connected by means of a flexible leatherstrap 33 with a sweep rod 34, which is provided with a Slot 35 forreceiving a. pin 36 whlch can be mounted in any one of a. series ofperforations 37 in the sweep `-check lever 38. A vroll 39 is mountedon-the sweep rod to bear on the sweep check lever to reduceI friction.The sweep check lever is pivotally mounted lon a bracket 4() which isfixed to the rock 'For this purpose it is provided with. a longitudinalSlot in which is located a'block 71, through which passes a. stud 72 onthe bracket 4U. Fixed to the bracket is a link 73 which is connected'with a pin 74 to which are pivoted links and 76. The link 475 isconnected with'the stud l72 and the link 76 with the lower end of thepicker Consequently the operation of 'the roll l42` on the lever, 43will cause the latter to fallfand rise at the bottom tocompensate forthe opposite motion at the top. This keeps the top vvin fixed relationtothe picker and prevents rubbing.'

The bracket 40 has a brace 44, which supe,

details of construction shown ports a box guide 45, not shown completelyherein,as any ordinary formof box guide can be employed. To the brace 44is con'- nected one end of a spring 46,'the other endl of which isconnected with a lever 47 pivoted 7'0 on the axis ion which the pickerlever is pivoted, and vhavin a roll 48 `for engaging the latter tonormal y force it back, and also to swing' the sweep check lever andpicking sweep arm in opposition to the action of.` 75 the picker roll.It is this spr-ing which turns the picking shaft after it has beenoscillated by the picking roll. The picker lever extends upwardly intothe picker 50, which is mounted to slide on one or more '8 guide rods51. These are preferably made hollow as indicated in Fig'. 6, and haveopenings 52 therein, and a slot 53 in the top communicating withsaid'openings. Oil cups 54 are mounted on thc box guide 'communieatingwith the interior of these guide rods, so that the rods and theirgrooves are constantly sel'feluln'ieated. l

Tofrelieve the frame of the jar due to the outward stroke of the pickerlever a brake is provided, comprsing alever S0 in position to be engagedby vthe picker, 'and normally pressed up by a spring 8.1. rI`his leveris shown as mounted on the brackets 82 which carry the rods 51. Q 95'The pickerl is provided with a cylindrical metallic shell 55 projectingfrom it,`and having a plug 56 thereinI for receiving the end of thcshuttle. Behind this shell and fixed on the shuttle check 58 is a bunter55) for 100 receiving the shell as it comes back. The shuttle check ismounted on a rod-60 and is provided with ,a spring 61 for an obviouspurpose. I It will be seen that the embodiment of the 105 inventionwhich has been described is of such a nature as to show that thisinvention is applicableto all styles of looms, and that it embodiesfeatures which render it more `durable than anything heretoforeV knownin 11d the art 'for this purpose, and-alsothatthe I other advantageswhich have been referred to herein can be obtained m a simple'andconvenient. manner. j

vWhile I have illustrated and described 11:1. one embodiment, ofthe`invention, II am aware. that many modifications may be made thereinby any'person skilled in the art, and that it maybe applied -in manyother ways without 'departing from the sco e ofthe in- 120 vention asexpressed in the claims.
